RPi Questions


Hi, I’m new but i have a big question;
Did can I implement a bluetooth module to let my pi function with other objects?


Yes, you can. You can use almost any off-the-shelf Bluetooth USB adaptor, even ones you might find in your local supermarket. There’s a list of compatible ones here: http://elinux.org/RPi_USB_Bluetooth_adapters

To get the Bluetooth configuration software you should try:

sudo apt-get install bluetooth bluez-utils blueman


Thank you :) I’ll serch for one.


Another question, con I connect a motor directly to the GPIO, or I need cables or a breakbord? If i need a breakbord whic one is best to control multiple motors?


Connecting a motor directly to the GPIO is a bad idea. In the simplest of terms, there just isn’t enough power coming from the GPIO pins to drive a motor, and attempting to do so will likely damage your Pi. This isn’t a silly or uncommon question, but it’s one with a lot of answers!

In order to drive a motor, you will need a motor driver board of some sort that you can safely connect to your Pi and a power source. A driver board takes the low-power signals from your Pi as instructions, and outputs much beefier ones that are capable of driving a motor.

The simplest and easiest form of motor driver to set up is an H-Bridge since this takes basic GPIO signals; ie HIGH/LOW ON/OFF.


I don’t know anything about DMX, but apparently it can be done with a USB->DMX controller, and possibly even more directly.

A quick Google turned up this guide: http://www.instructables.com/id/Raspberry-Pi-as-a-DMX-light-controller/

And yes, a Pibrella will drive a motor ( two, in fact ), although only in one direction!


So i need something like a pibrella;
And another question, con i use DMX with raspberry?


Thank you! I’ll try with all of these comunication systems.


Sorry does Pimoroni or Adafruit send items in Italy?
I want to buy a Pibrella, some wires, buttons and a display.


Yup! We ship to Italy.


Ok. Thank you. What is the breackboard(like pibrella) wich has mor OUTPUTS/INPUTS than others?


Does PiCamera NOiR comes with the blue gel by default? If not, were can I buy it?


I have the RoboPeak micro usb display, But i can’t let it work, what can I do?
P.S. I can’t download the necessary files.


You wont get far without the SD card image that RoboPeak supply. It’s the easiest way to get the display up and running properly- the alternative involves compiling your own Kernel, and that’s no small task!

Try this download link and let me know if it works for you: http://tinyurl.com/robopeak-sdcard-image


Did it works with raspbian?
And after the download what did i do?


It is working, after i just need to replace the content of my sd card or I need to do something else?


You need to boot that image to run the screen - it has the display drivers built in. If you replace it with any other image, it wont work.


How did i do this?
I need to place it into the sd card or i need to do something else before.
